HEATING APPARATUS.

Application filed December 16, 1926. Serial I To..155,142.

My invention relates to that class of port able heaters which consist of a heat ngveiement withina flue of which the heating eroment may be an electrical resistance, Bunsen flame, slow burning carbon compound or the like, while the t1 ue may be{ a tube of any mas terial preferably non-combustible and compartively a non-conductor of heat, and its objectis to provide a ready and effective, adiustment of both the temperature and rate bf flow of the current of hen tee an emerging from the flue.

To the above ends, my invention cons sts of a flue or tube pivotallysupported and provided with means for locking it in any desired adjusted position, means for securing a heating element at oneend thereof, and an adjust-able heat distributor at theopposite end. 1 For the purpose of illustrating my invention, I have shown in the I accoi'npanymg drawings one form thereof which s atvprcsent found in practice to give satisfactory and-reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that my invention is not limited to the precise arrangen'ient and organization of the instrumentalities as herein shown and described.

Fig. 1, represents a perspective View of a heating apparatus embodying my invention.

Fig. 2, represents a'longitudinal, sectional view of the flue of my novelheater, shown in elevation.

Fig. 3, represents on an enlarged scale a section on line 33 of Fig. 1.

Similar numerals of reference indicate corresponding parts. v

.1 designates my novel portable, electric heater consisting of a heating element 2 adapted foreonnection to a source of electric power, su )ported'within and attached to an open ended tube or flue 3 having a distributer 4 at the end opposite to the heating element and adapted to interfere with the normal flow of hot air emerging from the flue. 5 designates a stand or support having an upright 6, in which is mounted an adjustable screw 7 passing through the support 6v and threaded into the tube 3 for the-purpose ofelampin said tube to said support at any desired angle in relation to the horizon.

It will be understood that upon clamping the tube 3 with its essential parts consisting of the heating element 2and the distributor 4 to the, support 6 in a vertical position, the air within the tube on being heated by means of. electric energy applied to the heating element will emerge from the tube at maximum velocity, whereas upon clamping the tube 3 to the'support 6 at an angle of say 45 degrees in relation to the horizon, the rate of-flow of hot air from the tube will be reduced, while the temperature of such air as emerges will be increasedas compared to therate of flow of air and the temperature thereof attained when the tube 3 is operated as a heating de- V109, in the vertical position.

Similarly the rate of flow of air through the tube will be decreased and its tempeiatu ro increased as the angle of the tube in relation to the horizonis decreased and vice versz.

It may be desirable to distribute or spread the stream of hot air emerging from the tube preferred by me, since the same has been O as to produce a current of w an. of

I tributer 4 consisting of a core or cone 8 formedof sheet material, having a hole or. holes Qtherein to allow the-passage of a small proportion ofthe hotter air therethrough, while the major portion of the hot air passes over and around the cone, thus becoming spread and admixing with the cooler airof the surrounding atmosphere with the effect ofproducing a current of relatively warm air of larger cross-sectional area than would be obtained without the. use of the distributer. The distributer 4c is slidably supported within the tube 3 by arms or strips 10, which may be formed integrally with the materialof the distributer or attached thereto and are adapted frictionally to engage the tube 3 by their inherent spring action, thus permitting adjustability of position of the tionally engage the inner Wall of the flue as will be understood from Figures 1 and 2 said arms 18 being in tight frictional engagement with the flue so that the heating unit, spider and arms as a unit can be readily assembled. If desired resilient arms 13 can be fixedly secured to the flue as by riveting, spot Welding or other means. I

It will now be apparent that Ihave devised a novel and useful construction of improvements in heating apparatus Which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description and while I have in the present instance shown and described thepreferred embodiment thereof Which has been found in practice to give satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In a portable heater of the flue type, a fine, a heating element therein and means for adjusting the position of said'fiue for varying the temperature and rate oi? How of the heated air without varying the current flow in said heating element.

2. In a portable heater or the open ended flue type, a line, a heating element at one end thereof, means for adjusting the position of said flue for Varying the temperature and rate of flow of the heated air without varying the current flow in said heating element and means for deflecting and distributing mounted in the other end thereof, the apex of the cone being adapted to be positioned Within said line, and resilient arms attached to the distributer and in frictional contact with the wall of said flue. V

5. In a portable heater of the flue type, an adjustable fine, a heating element therein, and means for varying the angular relation of the fine to the horizon, thereby adjusting the temperature and rate of flow of the heated air.

' 6. In a portable heater of the flue type, an adjustable line, a heating element therein, and means for varying the angular relation of the flue to the horizon, without varying the current flow in said heating element,

thereby adjusting the temperature and rate of flow of the heated air.

7. In a portable heater of the flue type, a line, a heating element therein, and means for varying the angular relation of the fine to the horizon, Without varying the current lioW in said heating-element, and a, distributer mounted in the end of said flue opposite to the heating element.
